摘要:

视觉有意义图像加密方案(VMIE)由于能够将加密图像隐藏在明文图像中而不会引起攻击者的怀疑,受到了研究人员的关注。为了提高系统在容量和安全性方面的性能,提出了许多基于压缩感知的VMIE方案。然而,在这些方案仍难以有效解决密钥管理问题。为此,提出了一种基于孪生物理不可克隆函数和压缩感知的VMIE方案。首先,将完整的密钥种子嵌入到载体图像中,以实现公共网络密钥交换并避免额外的通信消耗。由于密钥种子经过了加密和编码操作,安全性和鲁棒性得到了保证。随后,使用哈希算法迭代扩展密钥种子以生成密钥流。实验结果表明,该方案可以实现安全性、嵌入容量和鲁棒性的平衡。

Abstract:

The visually meaningful image encryption (VMIE) scheme has attracted the attention from researchers due to its ability to conceal encrypted images in plaintext images without raising suspicion from attackers. In order to enhance the performance of the system in terms of capacity and security, many VMIE schemes based on compressed sensing have been proposed. However, it remains difficult to solve the key management problem effectively in these schemes. Therefore, a VMIE scheme based on twin physically unclonable functions and compressed sensing was proposed. First, the complete key seed was embedded in the carrier image to achieve public network key exchange while avoiding additional communication consumption. With the key seed being encrypted and encoded, both security and robustness were guaranteed. Subsequently, the key seed was iteratively extended using a hash algorithm to generate the key stream. The experimental results demonstrated that the scheme can achieve the balance of security, embedding capacity, and robustness.

Key words: visually meaningful image encryption, compressive sensing, physical unclonable function, hash chain
